通过文献资料法和调查法,对城市新生代农民工健身行为进行了调查研究。结果发现:新生代农民工参与体育健身活动的频率较低、持续时间较短、活动强度不大,健身活动内容对运动技能和运动场地要求较低,在开放性场地健身活动为主,体育消费水平较低。工作时间较长,缺少健身时间、健身器材和健身运动指导等对新生代农民工健身影响较大。为更好促进城市新生代农民工参与健身活动,需要加大社会支持力度,保障新生代农民工的合法权益;建立政府、社区、企业多层次的体育健身服务体系;加强城市公共体育设施建设和对公众的开放;开展多样化企业体育健身活动和竞赛等。 相似文献

北京城区教师体育健身研究 总被引：1，自引：1，他引：0
运用文献资料法、调查研究法、数理统计法等对北京市城区教师体育健身活动的状况和特点进行了研究.结果表明,北京市城区教师体育健身状况不容乐观,经常参加体育健身的教师和达到体育人口标准的教师较少.影响教师参加体育健身活动的主要因素是工作负担重、场地设施收费高、没有场地和缺乏兴趣等.建议相关部门提高教师健身意识,树立终身体育观;建立和形成教师健身的制度,开展丰富多彩的体育活动,提高教师的参与意识;充分发挥家庭和社区的作用,提高教师参与健身活动的程度;有针对性地加强教师健身所需场地、器械的开发和利用. 相似文献

基于相应的国家规范,通过行业部门普查、抽样调查、统计分析以及满意度指数分析等一系列调查和分析研究方法,对大连市城乡居民健身休闲与体育消费进行调查。研究认为大连市群众性健身休闲活动成效显著;体育消费已实物型为主,参与型和观赏性体育消费为辅;时间不足是限制城乡居民参与体育健身活动的主要原因。建议进一步增加政府在群众性体育活动方面的投入;贯彻《全民健身条例》,普及全民健身活动,提高居民参与健身活动的积极性,促进体育消费以及体育产业发展与提升。 相似文献

This study examined the effect of carbohydrate ingestion on metabolic and performance-related responses during and after a simulated 1h cycling time trial. Eight trained male cyclists (VO 2 peak = 66.5ml kg -1 min -1 ) rode their own bicycles mounted on a windload simulator to imitate real riding conditions. At a self-selected maximal pace, the cyclists performed two 1h rides (separated by 7 days) and were fed either an 8% carbohydrate or placebo solution. The beverages were administered 25 min before (4.5ml kg -1 ) and at the end (4.5ml kg -1 ) of the ride. With carbohydrate feeding, plasma glucose tended (P = 0.21) to rise before the time trial. Compared with rest, the plasma glucose concentration decreased significantly (P < 0.05) at the end of both rides, with no statistically significant difference being observed between treatments. Thereafter, plasma glucose increased significantly (P < 0.05) at 15 and 30 min into recovery, and was significantly higher at 30 min during the carbohydrate trial compared with the placebo trial. No significant changes in plasma free fatty acids were observed during the ride. However, a significant increase (P < 0.05) in free fatty acids was found at 15 and 30 min into recovery, with no difference between trials. Mean power output was significantly (P < 0.05) greater during the carbohydrate compared with the placebo trial (mean - S.E.: 277-3 and 269-3W, respectively). The greater distance covered in the carbohydrate compared with the placebo trial (41.5-1.06 and 41.0–1.06km, respectively; P < 0.05) was equivalent to a 44s improvement. We conclude that pre-exercise carbohydrate ingestion significantly increases endurance performance in trained cyclists during a 1h simulated time trial. Although the mechanism for this enhancement in performance with carbohydrate ingestion cannot be surmised from the present results, it could be related to a higher rate of carbohydrate oxidation, or to favourable effects of carbohydrate ingestion on the central component of fatigue. 相似文献

The biology and medicine of rowing are briefly reviewed. Effort in a 2000 -m race is about 70% aerobic. Because the boat (and in some instances a cox) must be propelled, successful competitors are very tall, with a large lean mass and aerobic power. Large hearts may lead to erroneous diagnoses of a cardiomyopathy. Large respiratory minute volumes must be developed by chest muscles that are also involved in rowing. The vital capacity is typically large, and breathing becomes entrained. Expiration cannot be slowed relative to inspiration (as normally occurs at high rates of ventilation) and the limiting flow velocity may be reached, with the potential for airway collapse. Performance is strongly related to the power output at the ‘anaerobic threshold’, and lactate measures provide a guide to an appropriate intensity of endurance training. Peak blood lactate levels are higher in males (commonly 11–19 mmol·l -1 and occasionally as high as 25 mmol·l -1) than in females (9–11 mmol·l -1), probably because males have a greater muscle mass in relation to blood volume. The skeletal muscles are predominantly slow twitch in type, developing an unusual force and power at low contraction velocities. Many rowers have a suboptimal diet, eating excessive amounts of fat. Lightweight rowers also have problems of weight cycling. Aerobic power and muscle endurance often change by 10% over the season, but such fluctuations can be largely avoided by a well-designed winter training programme. Injuries include back and knee problems, tenosynovitis of the wrist and, since the introduction of large blades, fractures of the costae. 相似文献

A regression analysis of competitors' tournament results in relation to their world rankings was proposed to identify the effect of home advantage in international ‘grand-slam’ tennis and ‘major’ golf tournaments. The results provided little evidence of home advantage in either the grand-slam tennis or the golf tournaments held in 1993. The only possible evidence of home advantage was found in the Wimbledon tennis and the US Open golf championships. Even these findings can be explained, at least partially, by (1) the availability of information concerning the low world rankings of the British tennis players competing at Wimbledon, and (2) selective entry, allowing only the world's top-ranked foreign golfers into the US open golf tournament. In both cases, the lower ranking home competitors have a greater opportunity to perform above their anticipated world rankings. Therefore, provided entry into tennis and golf tournaments is truly ‘open’ to both the host nation's representatives and foreign competitors alike, home advantage does not appear to be a major factor influencing the competitors' performance in such competitions. These findings may be explained by the relatively objective nature of the scoring systems used in tennis and golf, unlike the subjective influence of refereeing decisions on the results of team-games such as soccer. 相似文献
